It provides LI protection — long-time overload and instantaneous short-circuit — with a trip unit rating adjustable from 800 to 4000 A, rated for 690 V AC at 50/60 Hz per IEC 60947-2. ## Protection and coordination features Long-time pickup (Ir) is adjustable across 9 settings from 0.4 to 1.0 x In, with a corresponding long-time delay adjustable from 0.5 to 24 seconds at 6 x Ir (accuracy 0 to -20%). Instantaneous pickup (Ii) is also adjustable across 9 settings, covering 1.5 to 10 x Ir with +/- 10% accuracy. Zone selective interlocking (ZSI) is built in, enabling coordinated tripping in a selective system — downstream faults clear instantly while upstream breakers wait for their delay, keeping the healthy part of the plant online. ## Measurement, display, and diagnostics The unit measures instantaneous current on all three phases and neutral (I1, I2, I3, In) across a 0.2 to 1.2 In range with +/- 1.5% accuracy, and logs maximum current. A digital display shows fault indications for overload, short-circuit, earth fault, and internal fault. ## Pole configuration and neutral protection The ENW21412 supports 3-pole and 4-pole breaker configurations with the neutral on the left. Protected poles can be set to 3D (three poles, no neutral protection), 3D + N/2 (neutral protected at half the phase pickup), or 4D (all four poles protected). This flexibility lets the same control unit serve solidly-grounded, impedance-grounded, or corner-grounded delta systems without a hardware change.","metaTitle":"Schneider Electric ENW21412 EasyPact NW Trip Unit, 800-4000","metaDescription":"Schneider Electric ENW21412 Trip System 2.0A control unit for EasyPact NW drawout breakers.
